Abstract:

The instrumentation to build a complete eye movement recording and visual display facility is centered on a Generation V, SDI Double Purkinje Image Eye Tracker which permits high resolution 2 dimensional eye movement recording in a 20 deg arc field without contacting the human subjects eye. Visual stimulation is produced on a high resolution color monitor which is driven by a video tape recorder or by digitally stored and processed images from the computer. Eye movement data from the tracker are digitized for storage, analysis and plotting by a PDP 1173 computer. The system is presently operational and we are beginning experimental work. The first experiments involve finding out why an accurate eye position signal is available for localization judgements requiring that the body be pointed at the target but not when judgements are made solely within the visual modality. Details are found in the original proposal. Equipment cost breakdown is included. Keywords Vision Visual perception Eye movement control.
